error[E0525]: expected a closure that implements the `Fn` trait, but this closure only implements `FnOnce`
--> $DIR/closure-origin-tuple-diagnostics.rs:9:13
|
LL | let c = || {
| ^^ this closure implements `FnOnce`, not `Fn`
LL | let s = s.1;
| --- closure is `FnOnce` because it moves the variable `s.1` out of its environment
LL | };
LL | expect_fn(c);
| --------- the requirement to implement `Fn` derives from here
error: aborting due to previous error
